For each hypervisor supported by OpenNebula, we will describe the necessary steps to install and configure it. Knowledge about them is highly recommended but it is not needed to achieve a working virtualization host. Having experience with at least one hypervisor helps a lot for better understanding of how things work (and how they don't). The suggested hypervisor for newcomers is KVM as will be outlined later, because it is easier to set up.
To use a particular host on our OpenNebula cluster, it is required to register that host in OpenNebula using the following onehost
command:
onehost command [args] [options]
The command with relevant available options is as follows:
$ onehost create hostname im_mad vmm_mad tm_mad vnm_mad
